Embodiment 1

[0047] Embodiment 1 of the present invention provides a method for managing a PDN connection. The core network control entity (such as MME) manages the PDN connection, such as figure 1 As shown, the method includes the following steps:

[0048] Step 101, the core network control entity determines that the user equipment enters an idle state.

[0049] Specifically, in the process of determining that the user equipment enters the idle state, when the base station device (such as eNB) finds that the user equipment has no data transmission, it will send an S1 UE Context Release Request (context release request) message to the core network control entity, cause ( The value of cause) is user inactivity (user inactivity); when the core network control entity learns that the value of cause is user inactivity, it determines that the user equipment enters an idle state.

[0050] Step 102, the core network control entity determines the specified type of PDN connection corresponding to t...

Embodiment 2

[0062] Based on the first embodiment above, the second embodiment of the present invention provides a method for managing a PDN connection, in which a core network control entity (such as an MME) manages a PDN connection, such as figure 2 As shown, the method includes the following steps:

[0063] In step 201, the MTC device uses the MTC SPECIFIED APN to request to establish a PDN connection, that is, sends a PDN connection request for the MTC SPECIFIED APN to the MME.

[0064] Step 202, complete the PDN connection establishment process by checking the subscription information of the MTC device.

[0065] Step 203, when the UE has no data transmission, the eNB sends an S1 UE Context Release Request message, and the cause value is user inactivity.

[0066] In step 204, the MME initiates a PDN disconnection (disconnection) process according to the cause value in the S1 UE Context Release Request message as user inactivity, and disconnects all PDN connections using the MTC SPECI...

Embodiment 3

[0068] Embodiment 3 of the present invention provides a PDN connection management method, and the PGW manages the PDN connection, such as image 3 As shown, the method includes the following steps:

[0069] In step 301, the PGW determines a specified type of PDN connection corresponding to the user equipment.

[0070] Method 1: In the subscription information of the user equipment, an APN identifier for establishing a temporary connection (that is, a PDN connection for short-term use) can be set for the APN. In this case, the PGW may receive a notification from the core network control entity, and when the specified first identifier is used in the notification to indicate that the PDN connection uses an APN for establishing a temporary connection, the PGW determines that the PDN connection is a specified type of PDN connection.

[0071] In the embodiment of the present invention, the network side can configure two types of APNs for the PDN connection of the user equipment acc...

Abstract

Disclosed are a method and a device for managing a PDN connection. The method comprises: a core network control entity determining that a user equipment enters an idle state (101); the core network control entity determining a designated type of a PDN connection corresponding to the user equipment (102); and the core network control entity deleting the designated type of the PDN connection (103). Embodiments of the present invention may effectively manage a PDN connection of a large number of MTC devices without the need of consuming a large number of resources, so as to save resources occupied by the PDN connection, and improve the performance of the entire system.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and equipment for managing PDN connections. Background technique [0002] In the existing EPS (Evolved Packet System, evolved packet system) system, the always-on feature of the PDN (Packet Data Network, packet data network) connection is proposed, that is, the PDN connection in the core network is always online. The PDN connection can be called persistent connectivity (persistent connection); therefore, once a PDN connection is established for UE (User Equipment, user equipment), within the life cycle of this PDN connection, the default bearer (default bearer) of the PDN connection will always exist. [0003] In the EPS system, the release of the PDN connection is determined by MME (Mobility Management Entity, mobility management entity), or by PCRF (Policy and Charging Rules Function, policy and charging rule function) or PGW (Packet Data Gateway, packe...
